What exactly is the difference between a surge protector and a fuse? Can a fuse protect the electronic devices from lightning instead of surge protector?

At least they know the answer if they wanted it.
One is “what exactly is in a ‘surge protector’ ? ”

An AC voltage/ current source, and an ac inductive load.
So, the voltage could go up to 500 volts, and the fuse will not open up.
Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.
It seems Mohan does not understand the difference between a comment and an Answer.

but this device (an Inductor) … impedes the rapid changes in the current.

These are simplified answers to the original question, and does not change anything I wrote above.

But… the neutral is now “floating” because of the 1 ohm resistance.

He then asserts :
But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).

A circuit breaker is similar, but is resettable.

The other is “what does a “fuse” do?”

so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.
Now when you have a certain ac resistance, then a current flows in a loop.

Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.
At one ohm, the resistor has a maximum of 1 watt power.
P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.

So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.

The third is lightning and “how it gets conducted into a home.”
And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.

These devices are installed between the “hot” and “neutral” and protective ground.

This is where this question deviates from being a 'generic' question, and becomes more specific.
“ A fuse is a device which protects the (circuit) against overload and short circuit.”
Lightning arrestor is a spark-gap device, and can be installed anywhere. What is important, is that the wire is thick enough to withstand the lightning bolt and conduct the energy away from the building.
This is an electronic circuit designed to clamp voltages so that the Voltage Potential that appears at the outlet is never going to exceed the nominal value.
This one hit behind the barn.
Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".

OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.
In schematic diagrams this is the symbol for a fuse:
nine
This is a high voltage low current spike that comes down the line because of the power poles being struck, and the voltage suppressors activating on the primary side of the transformer.
There are three different concepts here that are getting confused.
For this case there are devices called Metal oxide varistors (MOV).
(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).
[old diagram got deleted by accident]
This is where the MOV conducts again, and dissipated the energy.
There are two important concepts here.
One
This is 'the assistant's answer'
So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.
At the secondary, it is 1000 times less.)turns ratio). If it gets hit with a 100,000 volt bolt of lightning then the voltage arrestors conduct and clamp the voltage down to line voltage, ( but a small amount leaks down the line). This is the problem.
It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.
Because the load is inductive, the current lags the voltage.(by a bit).
But it can get overloaded, and no longer works.
He then describes Rainy Season and Lightning.
Barnstars:
It also is a device that limits the change in current flow.
There is no harm in having the surge suppressor along with the fuse in the circuit. The fuse will not open up until the current melts the link. This will take time, and in the interim, that jolt will get transmitted into the power supplies.
A fuse is a non-resetable over current circuit protector.
This is a photo where a lightning bolt took out a home's complete mains distribution box, and a lot of electronic gear as well.
This device then solves the entire problem.
the problem then depends on "how fast does the fuse operate?".
Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
Can the fuse protect the electronic devices from lightning instead of a surge protector.
but I think this circuit , shows a few more pieces.
so, what happens?

I post the exact comment here.

What does a fuse do?
2024–10–14 [Omar Gharbi Omar Gharbi ]
When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.
If the nominal power is 4,000 watts then the current at 230volts is 16 amps.
Once the voltage goes over 0.0650 volts, then this fact can be used to amplify the difference, and turn the circuit breaker off , furthur down the line. Essentially that is what a RCD/GFCI does, it compares the incoming current, to the outgoing current, and if the difference between the two currents is over 5mA, then it trips the circuit breaker.

He then describes the function of a fuse.
